No, it also involves sides of polygonal shapes, and their counterparts in 3 or more dimensional spaces.
Angles were known before trigonometry. Trigonometry was the study of angles and their relationship to shapes.
By using trigonometry
Navigation takes place on the surface of a sphere, and it involves angles and distances. Spherical trigonometry was developed from plane trigonometry so that navigators could find their away over the Earth's surface.
Angles in trigonometry are the same as any other angles. They are a measure of the separation between two lines which meet at a point.
That depends, what it is you know. For example, if you know two of the angles, you can use the rule that the sum of the three angles must be 180 degrees. If you know the sides, the calculation is different, and involves trigonometry.
In geometry, angles are studied mostly in relation to each other. In Trigonometry, angles are studied in relation to side lengths and triangles.
Whenever architecture involves the use of lines that are not on the x or y axis, it will involve trigonometry to calculate the length of lines and the angles they make from one another.One example is calculating roof pitch.
Trigonometry is used in the fields of design, music, navigation, cartography, manufacturing, physics, optics, projectile motion, and any other field which involves angles, fields, waves, harmonics, and vectors.
Use trigonometry depending on what type of triangle it is.
